Abstract
Examples relate to a receiver termination detection circuit for wireline datalinks. A transmitter circuit includes positive and negative output nodes coupled through a channel to a receiver. A detection circuit comprises programmable pull-up and pull-down resistors coupled to the output nodes, and voltage comparators with independent reference voltage inputs. A mode selection input selects between single-ended and differential detection modes. Control logic drives the output nodes concurrently in single-ended mode and differentially in differential mode. The comparator outputs are sampled after a programmable time delay to detect receiver termination. The circuit supports both AC-coupled single-ended and DC-coupled differential termination detection while maintaining common-mode voltage during transitions to normal operation.
